The Slim Jim Antenna
http://www.hamuniverse.com/slimjim.html

The Slim Jim is a Vertically Polarized Omni-Directional End-Fed
Antenna having considerable gain and this is concentrated almost
parallel to ground toward the horizon rather than skyward making
it more efficient than a ground plane type antenna by about 50
percent better.

Due to it's SLIM {Very Thin Shape} used in it's Design,
there is very little wind loading. It is fed with 50 ohm coax.

It uses a 'J' type Matching Stub (J Integrated Matching = JIM),

Hense the name SLIM JIM.

So could I make one of these Slim Jim Antennas
for the Shortwave 49 Meter Band ? ? ?
and just how Thin-and-Tall would it be ? ? ?

What About the "Slim Jim" Antenna ?
